| Abstract | ||
| In this work, scraps from fire-clay brick were used to make refractory mortar by adding Iraqi kaolin (Alduejlh Zone) at different percentage contents (21, 27, 32, 40 and 47%). By crushing and milling, the mixtures of kaolin stone and fire-clay brick scraps were converted into powders of different particle sizes. The specimens were made as disks for the measurements of bulk density, water absorption, thermal conductivity, specific heat capacity and bond strength. The specimens with 40% kaolin showed the best properties as they are closer than others to the fire-clay brick properties. | ||
